Patent CA-2209257-C (CA)
Inventor: CURRAN NEAL J
IPC: A61G5/10
Filed: 1997-06-27
Granted: 2002-02-26
Abstract: The  present  invention  is  directed  to  a lightweight wheelchair having adjustable wheel camber, adjustable toe-in/toe-out positions,  and  front-to-rear adjustment of the wheel assembly relative to the frame. The wheel camber is changed by removable camber tubes having plugs  in opposite ends with different  angular relationships.  The camber tube is removed from an axle tube,  rotated through one hundred eighty degrees,  and reinserted to change the wheel camber.  The location of the angular recesses in the camber plugs addresses minor toe-in/toe-out adjustments while rotation of an axle tube provided with indicia assures that proper toe-in/toe-out adjustment   is   provided   for   larger  wheel   camber adjustments.   The front to rear location of the wheels relative  to  the  frame  can  be  adjusted  via  a  single fastener on each side.  Moreover, the track width of the rear wheels can be adjusted in response to the change in wheel camber.

Abstract: A tent structure convertible from a hanging tent to a ground-based tent is herein described. The tent structure includes a top portion having slots, T- shaped connectors stitched into the base portion and resilient rods having ends arranged to be inserted into either the slots or the T-shaped members. For use as a hanging tent, the ends of the resilient rods are inserted into connectors on opposite sides of the tent such that the resilient rods extend across the base portion of the tent and the tent is then hung from support structure(s). As a result of this arrangement, the base of the tent is firmly supported by the resilient rods and the tent is supported above the ground. For use as a ground-based tent, the connectors are pivoted such that the connectors are adjacent to the sides of the tent and the resilient rods are inserted one end into a connector and a second end into a slot such that the resilient rods extend along the sides of the tent and support the top portion of the tent above the ground. The tent includes a harness and is arranged to be rolled up and sealed so that the tent can be carried as a backpack.

Abstract: An impeller pump with thermostatically adjustable guide vanes (4) is suitable for use as an automotive coolant pump. The pump is driven by a constant speed electric motor (1) and flow variation is controlled by varying the orientation of the vanes (4). Orientation of the vanes (4) is effected by a wax-type thermostat, which senses coolant temperature: flow is increased when the coolant is hot, and decreased as the coolant cools. The variable guide vanes (4) are mounted for pivoting about radial axes, and are located just upstream from the pump impeller (2).

Abstract: The embossing process is effected between a pair of embossing rollers provided with toothings of the same kind which comprise rows of pyramidal teeth extending in the axial and the circumferential directions. Compared to the theoretical pyramid shape, the heads of the teeth are flattened while the edges of the pyramids are cut. The rollers, which are mutually displaceable in the axial direction, are thus able to catch in a stable mutual position of maximum penetration and to remain in this position in operation. This allows a safe mutual synchronization of the rollers and an optimal embossing of any kind of materials, especially of paper foils.

Abstract: L'invention porte sur un ensemble (10) d'instruments dentaires pourvu d'un mécanisme de commande (28) dotées de surfaces (50, 60) de came s'engageant l'une dans l'autre et conçues de façon à être en contact constant en utilisation. Le mécanisme (28) comprend un arbre de commande (30) doté d'une surface d'entraînement (50), et un autre arbre de commande (40) doté d'une surface menée (60). Les surfaces de came (50, 60) sont formées transversalement ainsi que les arbres (30, 40) juxtaposés transversalement l'un par rapport à l'autre de sorte que la surface d'entraînement (50) et la surface menée (60) soient en contact constant lors de la rotation de l'arbre de commande (30) de façon à communiquer une rotation oscillante à l'arbre mené (40). Spécifiquement, la surface d'entraînement (50) est conique et a de préférence un axe conique (51) d'approximativement 45 DEG  par rapport à l'axe de rotation (31) de l'arbre de commande (30). La surface menée (60) possède alternativement des bosses (62) et des creux (64). La rotation de l'arbre de commande (30) provoque le chevauchement de la surface d'entraînement (50) alternativement le long des bosses (62) et des creux (64) qui restent en contact avec la surface menée (60). Lorsque la surface d'entraînement (50) se déplace le long d'une bosse (62), l'arbre mené (40) tourne approximativement de 45 DEG  à partir de la position de repos, le contact avec les bosses opposées provoquant une rotation en sens inverse. La rotation oscillante est par conséquent communiquée à l'arbre mené (40) au moment où la surface d'entraînement (50) vient en contact alternativement avec les bosses (62) et les creux (64).

Granted: 2007-02-27
Abstract: The invention relates to the maintenance of safety devices. Valves and similar automatic mechanical safety devices normally maintaining a fixed position are in danger of getting stuck, and consequently may not be fully operable in an emergency situation. In a system according to the invention, real-time data indicating the operability of, for example, a valve actuator, is provided. When a fault is discovered, it can be localized using online diagnostic tools. A standby state is continuously maintained, as the unit for activating the safety function is independent of the unit for monitoring the operability, and the latter is bypassed in an emergency situation.
